5700 GPS Receiver Operation
30.2 Antennas
The 5700 receiver should normally be used with a Zephyr or Zephyr
Geodetic antenna, which have been designed specifically for use with
the 5700 receiver.
Use Figure 3.14 as a guide for measuring the height of the Zephyr and
Zephyr Geodetic antennas. The Zephyr antenna is designed to be
measured to the top of the notch. The Zephyr Geodetic (shown) has
been designed to be measured to the bottom of the notch.
Figure 3.14 Measuring antenna height
Older models of antennas, such as the Choke Ring or Micro-Centered™
L1/L2 antennas, need more power to operate than the Zephyr models.
To configure the receiver to output more power on the antenna port,
select the correct antenna type in the GPS Configurator™software, or
through the Trimble controller. For information on how to do this,
contact your local Trimble Service Provider.
